I know people for whom this means only terror, but since childhood I have always loved drive-through car washes. They're noisy, exciting, loud and a little scary as you wonder whether all the car waterproofing will hold. So, because it was a pleasingly silly thing to do, I took the camera with me on Sunday when I went to the local Jet petrol station clean the bird crud off Beloved Other Half's motor. Look on this less as an exercise in skilful photography, and more as an attempt to capture a moment of childish thrill.
